FISCHER, OF CHICAGO, ILLINOIS, ASSIG-NOR TO THE PHILIP CAREY MANU- Y FACTURING COMPANY, A CORPORATION F OHIO I' RAILV FILLEB Application filed August`21, 1926. Serial No. 130,688.

My Vpresent invent-ion relatesin general to paving and the like projects, and has particular reference to a vmeans for insulating the rails of car tracks when the same are embedded in city streets and other like places,

ywhere it is desirable to muile-noise as much as possible, and-'also absorb vibrations so as to protect the paving material, and also compensate for lexpansion and contraction of the rails and the paving material.

When I v refer to insulating material or vinsulating' means it should-be considered that Ihave in mind insulating against noiseV as well as `.against vibration, and also against expansion and contraction. f In other words,

the material forming the basis for my present invention is capable of acting lin this capacity inthe most acceptablemanner. vOne-of the objects of myinvention resides in providing rail llers of relatively short Vsections adapted'to beinserted between the `head and baseof a rail, andwherein each section is provided with a weakened portion, lsuch for instance, as a groove, whereby the section may be hammered into positiony because of the yielding nature of the section due to the groove, and which groove is adapted to receive an interlocking member, the arrangement being such thatthe interlocking member will interconnect the ,adjacent sections, whereby not only to hold them in position but also to'hold each section tightly Vin position between the head and base ofthe rail.

To clearlyl describe -my invention I` will refer to the preferred embodiment of the same illustrated in the accompanying drawing, -in which Figure l'is a perspective view of a`section of an ordinary T-head' rail, illustrating the application of n my invention 10 thereto.`

Y Figure 2 is a detailed perspective view of two abutting sections of the materialforming a part of my invention. Y

Figure 3 is a perspective view of a section of wedge used in combination with themate-` rial.

Figure 4 is a perspective view of a section of rail and paving material in which the rail is imbedded and illustrating the application of my invention.

For the sake of convenience I will refer to Y the material as a rail filler, and in constructing the same I prefer to make the filler in preformed sections 5, which, Y when installed along one or both sides of the rail 6 .will u su- .55y ally be arranged with the ends of the sections in abuttin relation as at 7. Each section will be pre ormed to correspond to the spaces along the rail web 8 thatV it is adapted to fill. The upper edge 9 of each section'will conform :50 to the shape of the underside of the rail-head l0, and the lower edgell of each section will be made to conform to the top side of the rail base :12.y For the most part the outer sides of the sections will be made perpendicu-` 65 lar and the thickness of thesamey should at least be Suflicient to present the outer wall flush with'the side of the rail head 10..

. The shape of the preformed sections may be modified inthe eventthat the filler is used `i170 with rails having flanged heads, but such modifications in the design in no way affects the principle of the invention. ForV this reason Ihave not thought it necessary to show the filler in combination with anything (5 more than an ordinary T-head rail.

' The preformed sections of filler may be made from any material suitable for the purpose, and as an acceptable composition I would suggest a mixture of oxidized asphalt, 80 having incorporated therein fibrous material, such as, roofing scrap (which for the most part is nothing more than saturated felt, al-

though lcontaining gritty particles or some lime stone), sawdust, ground corn cObS, g5 shoddy dust, or any other such materials Vto make upa more or less readily deformable, compressible mass, having the inherent qualities of compensating' for expansion and contraction, absorbing shocks, vibrations, capableof deadening sound-and, of course, being waterproof.

The most convenient method of preforming the sections would be an extruding machine, and vfor this reason in selecting a mixture care should be taken that a composition is decided uponthat can be accommodated by an extrudingV machine. Of course this is not 1mportant since the sections could be otherwlse v molded, but `not to as good advantage as would be produced by an extruding machine.

The composition referred to in a co-pending application Serial Number 79,543, filed January 6, 1926, for the same general class of invention, would be acceptable for turning out the sections of the present invention.

In installing the sectional` liller it should be set in place with suiiicient force to make it snugly fit the spaces in the` rail, in fact it shouldl be wedged` inplace. Not relying on this snug lit to retain the sections intact l propose to interlock the same with sections of wooden strips 14, the same being bevelled along the opposite longitudinal edges 15, so as to fit the dove-tailed recesses 16 in the sections 5 of the filler.

I lordinarily `prefer to arrange the strips 14 in each section of liller, so that the abutting ends 17 of the strips will overla the abutting ends of the filler sections. n applying the strips 14 they would be slipped inthe end of the recesses and driven in the same until the end of one section abuts the end of a pre-k viously driven section, indicated as at 17. This arrangement will interlock the sections 5 together and hold them in alignment,and also aid the wedging effect to hold them snugly in place. The use of the wooden strips also serves as an abutment for the paving material, lwhich in the present illustration is shown' as blocks 18.

The' perpendicular walls along the rail made by the sections of filler present a surface outward to the paving, for instance, the blocks 18 and the wooden strips act as a reinforcing means so vas to prevent sagging of the ller and thus holding the pavingL in alignment. j

While I have shown and really described the filling material applied to opposite sides of the rail, in some instances, it may be only necessary, or even only possible to apply the same to one side. However, the sectionsfunction the same on one or both sides.

\ I claim: l i

1. A rail filler comprising a preformed section of a ductile compressible material, constructed and arranged to be inserted in position between the head and base of the rail, said section having a weakened portion so as to permit the sections Vto yieldV when ham,- mered into said position, said weakened portion being shaped to receive a reinforcing member, which, when in position, will be interlocked therein and lock s-aid section in position between the head and base of the rail.

2. A rail filler comprising preformed sec- 'tions of ductile material, adapted to be positioned-between the head and base of a rail and inregistration with the adjacentends of the'sections abutting, each section having a weakened portion extending longitudinally thereof, with the weakenedportions registered, whereby to assist in positioning the sections between the head and base of the rail,

and an interlocking member adapted to be inserted and positively secured in said weakened portions for interlocking said sections.

3. In combination with a rail having a head and a base projecting from the side surface of the rail, rail filler sections of compressible material, said sections being formed with means for permitting temporary deformation ofsaid sections to facilitate their positioningj between the head and base of the rail, and a member adapted to be positively associated with said deforming means, whereby to lock adjacent sections in position and togethen 4.
